I don't have one myself, but in my pf experiences, I'm excited to see her on a defense team. Her drain isn't terrible, but it's never seemed to make the difference between a win or loss. What really seems to kill her usefulness to me is the second part of her SA, where she drains hp from her teammates. I've seen a lot of people defending this and saying it makes her great, but honestly, that doesn't even sound good on paper. Unless the rest of your team are soloists focused on healing, maybe a Diva Intervention, then once that SA triggers your team is kinda screwed. Even with a self healing back up team, is her damage worth having her at all?
